I once had an aluminum wheel with a very slow leak located in the center. I had the tire removed then I gave the wheel a heavy coat of rattle can black around the center. Never leaked again.
Don't know if that would work on a steel wheel, but it wouldn't hurt to give it a try.

Thanks Jim,
I'm expecting with tire removed I could have the weld repaired from inside wheel, or 2 part epoxy over the very small (<1/64") leak spot and get it to hold....

Just not sure of safety factor of repaired wheel and not wanting to go through this needless flat tires on the road...ever again. Especially after spending cash on new rims, tires, balancers just to avoid such...this will be last wheel purchased from this source.

Already carry 2 spare tires (experience learned on AlCan Highway)

Perhaps it becomes my 3rd spare tire/wheel and check air every stop.

Any one else have new factory welded steel wheel air leaks, without damaging wheel?

I had an old steel wheel that had rusted where the "bead" of the tire seals in the rim. Couldn't fix it... I put goop of all sorts but it must have a "porosity" issue somewhere. So, that meant it was still rusting... Somewhere I couldn't see and when it was rolled that must have "opened" up the spot enough to leak the air.

Walter,
Sorry to hear you are having trouble with your Steel wheels leaking.
We also have a 1964 Safari which had steel wheels when we purchased her. I understand you have purchased new steel wheels already, however you might try changing to aluminum wheels. I changed to aluminum wheels for all my tires (load range-E) including 2-spairs. Knock on wood, never had another problem.

I expect a dab of aircraft epoxy would seal the air leak, with tire off, and make a viable spare,spare for road trips.

I bought these 2 made for trailer wheels new in 2013...after 2 Goodyear Marathon catastrophic failures and just because I didn't want to trust the original old wheels anymore...the old ones never leaked, rolled fine...just were 50 years old and had found every pot hole from Arizona to Alaska and back.

How do you carry two spares on a '64 Safari?

I have one upright in front, behind propane tanks and other under front dinette floor area (in original hanger). Third may go on roof of tow vehicle, under wood canoe.

Walter,

I purchased my tires and aluminum wheels from Americas Tires, here in Modesto, CA.
I purchased a under the trailer spare tire carrier from Air Stream. Here is a link so you can see one, ours looks like this only it is shinny new.http://www.airforums.com/forums/f36/...ody-89012.html I keep the other spare on the floor inside the trailer or in the back of the tow vehicle. I have an 17' aluminum canoe and skybox on the top racks.
I also put a front hitch on the Yukon so I have more options, cargo, bikes, backing into super tight spots when booney camping.

My wife drives a '98 Camry with factory alloy wheels. One has a defect in the wheel like a bubble in the casting. Leaks pretty fast like flat in a couple of weeks. The leak is near the center so I applied a little epoxy. Twice.
